目的：探讨拉力螺钉联合接骨板对踝关节骨折并发下胫腓关节分离的临床治疗效果。方法选择漯河市中医院2011年3月至2013年12月收治的80例踝关节骨折合并下胫腓关节分离患者为研究对象，随机分为对照组和观察组，每组40例，对照组行保守治疗，观察组行拉力螺钉辅以接骨板治疗，对临床疗效进行分析。结果观察组治疗后下床活动时间、出院时间与治疗时间均短于对照组，差异有统计学意义（P <0.01）；对两组治疗1个月后，观察组优良率为92.50%，对照组为72.50%，差异有统计学意义（P <0.01）。结论对踝关节并发下胫腓关节分离采取拉力螺钉联合接骨板治疗是一种安全性高、效果显著的治疗方式，值得临床进一步推广使用。“,”Objective To investigate the clinical efficacy of lag screws supplemented with plate on ankle fracture combined with inferior tibiofibular joint separation. Methods Eighty cases of ankle fracture combined with inferior tibiofibular joint separation were selected and equally randomly divided into control group and observation group. The control group was treated with conservative treat-ment,and observation group was treated with lag screws supplemented with plate. The clinical efficacy was analyzed. Results After treatment,ambulation,discharge and treatment time of observation group were shorter than the control group(P <0. 01). One month after treatment,excellent rate of observation group was 92. 50%,and 72. 50% in control group,there was significant difference between the two groups(P <0. 01). Conclusion Lag screws supplemented with plate in treatment of ankle fracture combined with inferior tib-iofibular joint separation is a safe,significant effect treatment option,so it is worthy of clinical promotion.
